Phospholipids from bilayers because it is energetically favourable.
The hydrophobic parts don't like interacting with water molecules, so they interact with each other instead. The hydrophylic parts like interacting with water, so they form the outside of the layers and shield the hydrophobic parts of the membrane.

A cell is surrounded by water. There is also a lot of water inside.
A phospholipid has two ends: one is "comfortable" in water; the other is not. The result is that any phospholipids, even in a glass of water, will bring their "water-avoiding" ends together, and leave the "water-liking" ends on the outside. In short, phospholipids in the presence of water form a bilayer.
This applies to all cell membranes, not only the plasma membrane (the outer membrane), but also the endoplasmic reticulum and all other membranes in the cell.
The end of the phospholipid molecule that is attracted to water is called the hydrophilic head, and its polar nature is due to its phosphate group. The two fatty acid chains form the hydrophobic end of the phospholipid. The whole molecule is termed amphipathic, meaning that it has both hydrophilic and hydrophobic components.
What else can I help you with?
What kind of lipids make up the bilayer that form cell membranes?
Phospholipids
What molecules form the double layer of cell membranes?
A double layer of phospholipids makes up most of your cell membranes
What do phospholipids form?
Phospholipids form the basic structure of cell membranes. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves in a bilayer to provide a barrier that separates the interior of the cell from its external environment.
Cell membranes are composed primarily of what type of molecule?
Cell membranes are composed primarily of phospholipids. These phospholipids form a lipid bilayer that acts as a barrier to the passage of most molecules. Additionally, cell membranes also contain proteins, cholesterol, and carbohydrates.
The major lipid used to make cell membranes is?
The major lipid used to make cell membranes is phospholipids. They have a hydrophilic head and hydrophobic tail that arrange in a bilayer to form the cell membrane.
What are the different lipids that are in cell membrane?
Phospholipids are found in the cell membrane which form the bilayer
What is the material that composes the cell membrane?
The cell membrane is composed of phospholipids. They form a bilayer for the cell.
What kind of lipids make up the bilayer that form cell membranes?
Phospholipids
What cell structures are made primarily from phospholipids?
cell membrane
Which molecule are used to form cell membrane?
Phospholipids are the main molecules used to form the cell membrane. These molecules have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tail, allowing them to spontaneously arrange into a double layer known as the phospholipid bilayer that makes up the cell membrane.
What molecules form much of the cell membrane?
Phospholipids are the most abundant molecules in the cell membrane. They have a hydrophilic head and hydrophobic tails that arrange themselves in a lipid bilayer to form the basic structure of the membrane.
What kind of lipid make up the bilayer that form cell membrane?
Phospholipids, where one end is hydrophobic and the other is hydrophilic.
What molecules form the double layer of cell membranes?
A double layer of phospholipids makes up most of your cell membranes
What is an important of the phospholipids in the cell membrane?
They can form a lipid bilayer. The lipid bilayer is the barrier that keeps ions, proteins and other molecules where they are needed and prevents them from diffusing into areas where they should not be.The phospholipids help the cell maintain its internal aqueous environment. (Apex)
